`To all wha/m t may comem:

Be it known, ,that LFREDERIQKLLSHELQR, a` citizen of the UnitedStates, residingat Petersbi'irg, in the county of D inwiddieand State vof Virginia, have invenbedcertain new and ,useful Improvementsin Labeling Machines, of which the followingisaspei- -fication, reference beingnhadthereinto the accompanying drawing. Y

The resent :invention relates to machines or applying labels to lbottlesaml other objects, and appertains more especially to improvements and refinements of the bottle labeling machine disclosed in my Patent No 1,413,795, granted April 25, 1922.

It is the` object of the invention toim- `prove such machine in several particulars, in order to enhancer the utility and operation thereof, and to provide for benecial advantages. y

.One of the specific objects of the invention fis the provision of a novel and improved magazine for bottles orl objects from which they ,are suppliedonesatia time in 4succession for the application of labels thereto, and a further object in this connection, is to provide novel means for controlling the movement of the bottles or objects in the magazine, whereby to prevent breakage Vandato facilitate the proper transfer of the objects from .the magazine vto the conveying means.

Another object is theV improvement ofthe paste applying means in order to regulate the amount of paste supplied and to avoid excess paste.

A further object is the provision of ironing means for ironing or attening out the labels on the objects, and operating to supplymoisture to the outer surfaces of the labels opposite to the surfaces contacting with `the paste, whereby the labels Will lie ,Hat against the objects, and such moisture supplying means also serving to dilute or .Wash away any paste that is transferred to the ironing. members,.to prevent such irening members being gummed u when labels are refused. This feature is o .considerable advantage, inasmuch as the labels When moistened by paste on the inner surfaces thereof, have a tendency to curl, either lengthwise orcrosswise, Idepending upon lthe direction, of the grain of the paper, thereby causing, in some instances, the edges .er .este

Fi 29 is an enlarged fragmental View showing the clutch in section and itsoperating means.

The machine, in general respects, is quite similar to the machine disclosed in said patof the longitudinal median plane and slidable late-rally on the rods 23 mounted transversely on the frame. An adjusting screw 24 connects the tables 22, having right and left hand threads for moving said tables toward and away from one another, to obtain the desired adjustment.

The operating mechanism mounted on the frame comprises, generally considered, a bottle conveyor, bottle magazines, paste applying devices, label applying devices, and label ironing and moistening devices, which will be described in detail, and under captions with such titles in the order mentioned.

Bottle conveyor.

This conveyor, said term referring to the entire conveying device, includes an adjustable guide or track fo-r the bottles, comprising a pair of parallel longitudinal rails 25 above the adjacent portions of the tables 22. These rails are adjustable transversely with the tables and also adjustable up and down. Thus, screws or bolts 26 are threaded into the rails 25 at the outer sides thereof, and extend through vertical slots 28 of posts 27 having feet secured on the tables 22. Thus, by loosening screws 26,V the rails 25 can be adjusted verticall and each rail is sup-ported from a pair o posts 27. In order to obtain accurate adjustment and to support the rails 25 in their adjusted position, adjusting screws 29 are threaded within the feet or bases of the posts 27, as best seen in Fig. 27, and the heads of the screws 26 rest on the heads of the adjusting screws 29. The screws 29 thus support the screws 26 and rails 25, and said screws 29 can also be adjusted for raising or lowering the rails 25. The rails 25 have upstanding guide flanges 31 offset toward one another to guide the bottles B between them, and a longitudinal channel 30 is disposed between the rails 25 underneath the flanges 31 in which the upper run of an endless conveyor chain 32 travels. The flanges 31 have openings 31 in which the wheels of the paste, applying, label applying and ironing devices can move. The channel 30 is supported on transverse pins 30 secured to the rails 25, each pin being secured to one rail and projecting slidably through the other rail, tol permit of the transverse adjustment of the rails with the tables 22, in adjusting the anges 31 for bottles or objects of various widths or dimensions. The channel 3() being supported on the pins 30 redness which are carried by the rails 25, will be adjusted vertically with the rails, thereby raising or lowering the track or guide for the bottles, as desired or necessary for different sizes of bottles. The anges 31 provide the opposite sides of the bottle guide or track, while the channel 30 forms the bottom there-- of,`in which the conveyor chain 32 travels, for moving the bottles or objects with the chainalong the guide or track. Tte guide or track is ad'ustable as to Width and vertical position, or different sizes of bottles or objects, and to cause the bottles to properly cooperate with the paste and label applying devices. The channel 30 can b-e of wood or other similar material to provide a noiseless support for the chain, and also reduc-e friction.

The sprocket chain 32 passes over sprocket Wheels 33 at the ends of the machine beyond the ends of the guide or track, and said Wheels are mounted on transverse shafts 34, each of Which is carried by and journaled in a yoke 35 carried by a standard 36 Which is adjustable vertically in a guide 3T carried by a yoke or cross piece 38 secured on the beams 21 at the corresponding end thereof. The standards 36 are adjustable vertically for raising or lowering the upper run ol" the sprocket chain 32, according to the vertical adjustment of the track in which the chain and bottles mor'e. Thus, the lower end of each standard 36 has an ear 39 through. which an adjusting screw 39 extends, being threaded upwardly into the yoke or cross piece 38, or other suitable means can be used tor raising and lowering the standards.

The driving mechanism Jfor the conveyor chain 32 includes a sprocket Wheel 40 under which the chain 32 passes. A gear case 41 is suspended from a pair ot cross rods 42 secured to beams 21, and a drive shaft 43 is journaled through said vase, and has a pin ion 44 thereon Within the case meshing With a gea:l wheel 45 aiso within the case and secured on a counter shaft 46 journaled through the case. The sprocket wheel 40 ris secured on the shaft 46 for angular adjustment, such as by means of a set screiv 40,'in order that the sprocket Wheel 40 can be adjusted angularly for setting the chain 32 ahead or behind to advance or retard bottles or objects with resp-ect to the devices which they pass. l pulley Wheel 4i" is secured to the shall; i3 and is operated by a belt 48 driven from a transverse counter shaft 480 journaled to the forward portion of the traine Ell and said shaft 480 is driven by an electric motor 49 or other prime mover which.. as shown is supported on a shelf 50 supported from the frame 20, the armature sl'iaft et the motor beine' connected by a belt with pulley wheel 481 secured on the counter shaft 480.

.i clutch is provided between the sha tt 480 and belt 48 in order to enable the machine to be started and stopped at will of the operator. This clutch is shown iu detail in Fig. 29. A puiiey wheel 483 around which the belt 48 passes, is mounted for rotation l' on the shaiit 480 and has an inner annular lubricant channel 484 to which an oil duct 485 extends tor supplying lubricant. A collar 486 is secured or fixed ou the shaft 48u,

and has a telescopic Vtif` with the huh oi the wheel 483, and the said pulley Wheel 483 has a clutch rim 487 surrounding and concentric with the collar 486. The confrontn ing surfaces et the collar 486 and rim 48'? are provided with ribs or splines 488 and 489, respectively, such as used in disk clutches.` as Well known, and a set ol frirtion disks 49u is disposed between the roilar 486 and rim 48T. Every other disk engages the splines 488 of the collar 48o, and l contact, pulley wheel 483 is caused to ro tate with the shaft 480.

In order to control the multiple disk clutch, a sleeve 491 is slidably mounted on the shaft 480, and has au enlarged and oii set end portion 492 extending over one end portion of the collar 486 to compress vthe set of disks when the sleeve 491 is moved toward them. An annular plate 487 is preferably secured to the rim 4ST to enclose the disks. and the end portion 492 of the sleeve 491 slides Within said plate 487 thereby excluding dust and dirt from the disks. The clutch is normally closed by means of a coiled expansion spring 493 surrounding the sha't't 480 and located Within a lecess 494 oi1 the sleeve 491, and confined between the inner end of said recess and a collar 495lon the shaft 480 whereby the expansion of said spring will move the sleeve 491 to bring theidisks into frictional contact, thereby closing the clutch and driving the pulley wheel 483 with the shaft 480. The sleeve 491 is slidable on the collar 495, and said collar is adjustably secured ou the shaft 480, by means of a set screw 496, or the like, whereby said collar can be adjusted for regulating the tension ot the spring 493. A ring 497 is mounted for rotation on the sleeve 491, and a thrust collar'498 is screvi7 threaded or otherwise secured on the sleeve 491 and houses a ballor a'ntirictionalbearing 499 Which is disposed between the collar 498 and ring 497, thereby reducing friction when the ring 49T is moved away from the diskS,'to movethe collar 498 and sleeve 491 accordingly, to

release the disks and thereby open the clutch.

In order that the clutch can be conven iently operated from the rear end of the machine, where the operator or attendant is usually positioned, the ring 49T is pivotally connected to a t'ork 500 secured on a longitudinal rock shaft 501 mounted in the frame 20, and an arm 502 secured to said rock shaft is connected by a link or bar 503 with an arm 504 secured to an upper longitudinal rock shaft 506 extending along one of the beams 2l to a point adjacent to the rear end of the machine. Said shaft 506 is journaled in bearings 507 secured to said a beam. and a handle 5708 extends upwardly from said shaft at the rear end of the machine, whereby said handle can be conveniently swung to swing the arm 504 upwardly, thereby similarly swinging the arm 502 and swinging the fork 500 to move the ring 497 and sleeve 491 against the tension of the spring 493, whereby to open the clutch, and disconnect the pulley wheel 483 from the shaft 480, thereby stopping all the parts that are operated 'from the pulley Wheel 483 and belt 48. When the operator lets go of the handle 508, the spring 493 again comes into play for closing the clutch, thereby starting t-he machine again at once.

A second counter Shaft 5l is journaled through the case 41 above the shaft 46 and has a gear wheel 52 secured thereon within the case and meshing with the gear wheel 45 to be driven thereby. Secured on the opposite protruding ends of the shaft 5l are sprocket wheels 53 and a sprocket wheel 54 is secured on the shaft 51 in the median longitudinal plane ot the machine in which the conveyor chain 32 and guide or track are located, as well as the sprocket wheel 40.

At equally spaced intervals, the conveyor chain 32 is provided with lingers or lugs 55 projecting therefrom to contact with the rear ends or bottoms of the bottles and move them along the track within which the fingers project upwardly from the upper run of the chain.

The conveyorl also includes means tor holding the bottles down on the conveyor chain 32 and retarding the bottles slightly to hold them firmly against the lingers 55. Such means includes an arch or yoke 57 mounted for oscillation on the shaft 34 at the forward end of the machine, and carrying a shaft 58 driven from said shaft by means of sprocket wheels 59 and 6() on the shafts 34 and 58, respectively, and a chain 6l connecting the wheels. A pair ot' arms b'2 are mounted for oscillation. on the shaft 58 and project rearwardly within the arch 57 and carry the shaft 63 which is movable in arcuate slots 64 in the sides of the arch, whereby the shaft 63 can be adjusted upwardly and downwardly. In order to maintain the shaft 63 in its adjusted position,

clamp plates 65 engage said shaft at opposite sides of one side member of the arch, and said plates are connected by a screw er bolt 66, which can be tightened so that said platos clamp the side member of the yoke. thereby preventing the shaft 63 from being displaced upwardly or downwardly without intentional adjustment. A pulley wheel 67 is secured on the shaft 63 between the arms and an endless belt 68 passes around tit-e pulley wheel 67 and extends longitudinally over the track and upper run ol the chain 32. In order to support the belt 68. a red or tube 69 extends through the upper portion ot' the yoke 57. which has a vertical slot 70 receiving said rod for vertical adjustment, and the rod is secured to said yoke by means 0f nuts 70 threaded on the rod and bearing against the opposite sides ot the yoke. Said nuts 70 when loosened, enable the rod 69 to be raised or lowered for purpose ot' adjustment. The rod (39 extends longitudinally above the guide. and arch` shaped hangers 7l, of which there may be any suitable number, are suspended rom the rod 69. said hangers havingpinched clamps 72 embracing the rod 69 and made 'tast thereon by means of screws 7 3 or the like. The hangers 7l straddle the belt G8, and a pulley wheel 74, of substantially the same diameter as the pulley' wheel 67, is journaled within that hanger '7l at the tree or rear end of the rod 69 remote from the arch 57, and the belt 68 passes over the pulley wheels` at the limits et its travel. Smaller intermediate pressure wheels 71' located between the upper and lower runs of the belt 68, are mounted for rotary and Vertical movements within the remainingT hangers 71, the axles 7 6 ot said pressure wheels projecting within the vertical slots 77 in the limbs of the hangers. By looseningl the clamps 72, the hangers 71 and pressure wheels can be distributed to desired longitudinal points, in order that the pressure of the wheels on the lower run of the belt 68 Will be at such points most needed to hold bottles down firmly on the conveyor chain 30. The bottles are carried between the upper run of the chain 32 and the lowcr run of the belt 68, and the weight of the wheels 75 presses the belt 68 down to rest firmly on the bottles. The shaft 63 has a gear wheel 78 secured thereto meshing with a gear wheel 79 secured to a shaft 58, in order to drive the belt 68; and the gear wheel 78 is slightly larger in diameter than the gear wheel 79,whereby the belt moves at a slightly less speed than the chain 32, but in the same direction forward to convey the bottles. The belt 68 in traveling at a slightly less velocity than the chain 32 and in pressing on the bottles, retards the bottles slightly on the chain 32, and thus holds the bottles firmly against the fingers 55, to preplate. Standards 838 which are of U-sha e, similar to the bearing members 829, are a so supported on the rods 834 and the plate is secured on the upper ends of the standvards. The members 829 and standards 838 have sleeves 839 mounted slidably on the rods 834, for adjustment and secured to said rods by means of set screws 839 or the likeE The inner axle or shaft 827 is operatively connected with the corresponding shaft 34C by means of bevel gears 800 or the like, which are protected by a guard or shield 801.

In order to hold the remaining bottles in the magazine', when one bottle is' moved therewith onto theconveylor chain 32, so as to avoid the breakage of the bottles and to also eliminate noise, an automatic detent device is provided at the delivery end of the magazine.` This device comprises a horizontal plate 802 disposed over the delivery end of the magazine. and over the chain 32, as seen in Fig. 19, under which the bottles move, and this plate also serves to hold the bottles down in place as they move from the magazine to theychain 32. rihe plate 802 has an upstanding flange 803 overlapping a flange 804 depending trom a clamp 805 embracing the rod 68 naar the free or rear end. thereof, and bolts 806 clamp the flanges 80? and 804 together. Said ilanges have vertical slots 807 in which the bolts extend, enabling the plate 806 to be raised and lowered for bottles or objects of different sizes. That end of the plate 802 nearest the receiving end of the magazine is curved upwardly. as at 808. to serve as a deflector for pushing down the bottles as they move under the plate 802, thereby bringing the bottles into horizontal position before moving onto the chain 32. should the bottles be tilted slightly in the magazine.

. The detent means is mounted on the plate 802, and comprises a roet shaft 809 jour naled in bearings 810 on the plate 802, said shaft being disposed longitudinally over the delivery end of the magazine, or transverse-- lily over the chain 32. A rearwardly and downwardly extending arm 811 is secured to the shrill' 809 directly over the conveyor chain 32. and its rear end extends down wai-diy slightly below the horizontal plane ot the upper surfaces of the bottles in the magazine., beyond the shoulders or Jforward portions thereof, as seen in Fig. 17. A second arm 812 is secured on the shaft 809 by means of a set screw 812', or the like, to enable said arm 812 to be adjusted angularly and longitudinally` on the shaft. arid said arm has a downwardlybpening socket 813 inxwhich detent 814 is slidable upwardly anddownwardly. The plate 802 has a slot 814,nparallel withthe shaft 809 permitting ofthe Yadjustnru-ent of the arm 812 to difieryent, longitudinal'positions with respect to the magazine, for the proper contact ot the detent 814 with the bottle or object next to the one which is being removed from the magazine. A screw 815 passes slidably downward into the socket 813 and is secured within the detent 814, whereby to raise the detent with the arm 812 and limit the projection of the detent from the socketu The detent is yieldable, being projected by means of coiled expansion spring 816 within the socket confined between said socket and de tent, thereby enabling the detent to yield when brought to bear on a bottle or object underneath, as seen in Fig. 20. The arm 812 is adjusted to the proper angular and longitudinal position on the shaft 809, whereby when the arm 811 is swung upwardly, the detent 814 will hear on the bottle next to or following the bottlei which is on the chain 32 to he or in the act of be ing removed from the magazine, as seen in Fig, 20, whereby to hold the second bottle down tightly on the bottom plate, thereby preventing the belt 25, which operates continuously, from shifting the rear ends ot' the bottles toward the chain 32. which would occur otherwise, it the detent were not used. The shaft 809 has a third arm 81T secured thereto to swing with respect to a stem or rod 818 secured to the plate 802. and coiled wire springs 819 are disposed on said rod above and below the arm 817, the. lower spring bearing on the plate 802, and the upper spring bearing against a nut 819 secured on the upper terminal of said rod. The springs 819 provide for the yielding motion of the shaft 809 and the arms carried thereby, the upper spring 819 return ingl the arms to normal position when a bottle has passed from in under the arm 811. and the lower spring 819 cushioning the arms when returned to normal position.

The operation of the bottle magazine is as Jfollows: The belt 825 operates continu ously with the chain 32, and the upper run ot' the belt 825 moves toward said chain, thereby creating a tendency for the bottles in the magazine to move with the belt toA ward the chain. The bottles are placed in the magazine on the belt 825, and are moved by the belt against one another, side by side. as seen in Fig. 19. rllhe first bottle in the magazine is therefore shoved by the others from the delivery end ot' the maga zine onto the conveyor chain 32, as seen in Fig. 19, in rear of. the arm 811. as seen in Fig. 17. the spring buffer cushioning the bottle as it is moved over onto the chain 32. The bottle is moved onto the conveyor chain beto-re the next linger 55 reaches the magazine` and when said finger comes into contact with the bottle on the chain, the bottle is carried forwardly from the magazine into the conveyor track between the flanges 31 of the rails 25, the chain 32 sup- Sii
